Sorry for posting a new tread on this, but didnt get a response from anyone in the sts tread.
Has anyone had any experience with this engine and what engine in the novarossi line of engines is the d5r comparable in power to. Thanks.

this engine is the best for me,its very easy to tuned and the breakin process is way to easy,if compare with other its same with rb eng x12 back in 2002-03 but the part as piston liner and conrod can be fitted to novamega and rb x12 engine..and way to cheap..

thanks man for the reply, what break in process did you use, the last sts engine i had was a nightmare to turnover, burnt out my starter box.
